Question

Help!!.. Find the least common multiple of each set of three numbers? 6, 9 and 12

Answer 1

36 Because some common multiples of: 12 are 12,24,and 36 9 are 9,18,27,and 36 6 are 6,12,18,24,30,and 36. Each of them has 36

Answer 2

LCM = 36

Answer 3

thank you! but how do i get that?

Answer 4

Keeping finding multiples of everything you need to find a LCM of and when they all have a match, in this case that was 36, thats the LCM. so if it was 2, 6, 7 instead,
2's multiples are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42 etc etc, and
6's is 6, 12, 18, 24, 30, 36, 42, 48, 56, 60, etc etc and
7's is 7, 14, 21, 28, 35, 42, 49, 56, etc. etc. IF YOU SEE that the first # the three have a common is 42, therefore the Least Common Multiple LCM is 42.

Answer 5

can you draw it out for me just for example? sorry i need to picture this
6, 9 and 12

Answer 6

those are the multiples, the LCM is when all 3 have the same # for the 1st time.
